PROCESS OF POLISHING PLATED FLAT-WARE.

No Drawing.

To all whom it may concern:

Be it lmown that I, PIERREPONT B. Noxns, a citizen of the United States,and resident of Oneida, Madison county, New York, have made a certainnew and useful Invention Relating to Processes of Polishing PlatedFlat-Ware, of which the following is a specification.

This invention relates especially to processes for polishing platedflatware suchas knives, forks, spoons and the like, which have beenelectroplated with silver for example, so as to produce the usualornamental and protective coating. By strongly pressing theelectroplated flatware artlcles in planished dies the granular orfrosted electroplated layer is pressed down or condensed or possiblyflowed so as to produce a smooth, polished surface.

In carrying out this process the unplated spoons or other flatwarearticles, maybe given their final form and provided with the desiredornamental design as by stamping in dies which are preferably highlypolished or planished where a smooth, polished surface is desired in thefinished article. Then after such smoothing as seems necessary ordesirable these articles are electroplated so as to give them a coatingof silver or other precious metal of the desired thickness which in theusual plating processes has a frosted or unpolished appearance. Theplated articles may then be very readily polished by pressing themstrongly in planished dies, preferably the same dies in which theunplated articles were finally pressed and this may be done in anysuitable way as for instance in presses of varlous kinds used in thisart, preferably those in which heavy pressure and accurate aline-' mentof the dies can be secured and in which the dies are forced slowly homeupon the article, which minimizes wear of the dies and preserves thesurface of their planished portions and also seems to assist somewhat insecuring the desired polishing of the article. By subjecting theelectroplated articles to a slow, heavy pressure in the same finishingor design stamping dies used to form the unplated articles in the firstinstance, a smooth, polished or planished surface can be readily securedthroughout the desired extent of the articles at a single operationleaving little or no additional polishing to be done and greatlyminimizing the Specification of Letters Patent.

usual expensive hand buffing or other polishing methods necessary infinishing electroplated silverware in the customary manner.

This invention has been described in connection with illustrativemachines, devices, methods, processes of procedure, and orders of steps,to the details of which disclosure the invention is not of course to belimited, since what is claimed as new and what is desired to be securedby Letters Patent is set forth in the appended claims.

I claim 1. A process of polishing electroplated spoons and similarflat-ware articles which consists in gradually applying to theelectroplated articles a heavy pressure in the same planished dies whichwere used for the final design stamping of the articles before theywere. electroplated and in, simultaneously maintainingthe alinement ofsaid dies and articles and-in compressing and condensing theelectroplated layer on said articles and causing it to conform to thecontacting surface of the dies and thereby polishing the desired extentof the surface of the articles.

2. A process of polishing electroplated spoons and similarflat-warearticles which consists in applying to the electroplatedarticles a heavy pressure in the same planished dies which were used forthe final design stamping of the articles before they were electroplatedand in simultaneously maintaining the substantial alinement of said diesand articles and in thereby polishing the desired extent of the surfaceof the articles.

3. A process of polishing electroplated spoons and similar flatwarearticles which consists in applying to the electroplated articles aheavy pressure in planished dies and in simultaneously maintaining thesubstantial alinement of said dies and articles and in thereby polishingthe desired extent of the surface of the articles.

4. A process of polishing plated spoons and similar flatware articleswhich consists in gradually applying to the plated articles a heavypressure in the same planished dies which were used for the final designstamping of the articles before they were plated and in simultaneouslymaintaining the alinement of said dies and articles and in compressingand condensing the plated layer on said articles and causing it toconform to the contacting surface of the dies and thereby polishing thedesired extent of the sursimultaneously maintaining the alinement offace of the articles.

5. process of polishing plated spoons mg the desired extent of thesurface of the and similar flatware articles Which consists articles.
